    Israel’s defense export contracts were worth $7.2 billion in 2019

    By: Seth J. Frantzman JERUSALEM — Israel's defense export deals from 2019 totaled $7.2 billion and involved 120 different defense companies, according to the head of the Defense Ministry's International Defense Cooperation Directorate. The country's defense-related sales have been slightly declining over the last decade. Israel's defense export contracts in 2010 also totaled $7.2 billion, but was down to $5.7 billion in 2015. In his announcement, Yair Kulas said the large number of companies selling abroad “reflects the strength of the Israeli defense industry.” The former brigadier general added that he anticipated growth in government-to-government agreements in 2020, but noted that the coronavirus pandemic has “devastated the global economy and the defense sector.” Israel's three largest defense companies are Elbit Systems, Rafael Advanced Defense Systems and Israel Aerospace Industries. The local defense industry has experienced consolidation in the past few years, with IMI Systems now part of Elbit, and Aeronautics Limited acquired by Rafael. Ten years ago Israel was a world leader in UAV sales, but as its focus has changed, unmanned aerial systems now make up only 8 percent of the country's sales. Today's major markets for Israel are in radars and electronic warfare. The Elta ELM-2084 — the radar used in the Iron Dome air defense system — was sold to the Czech Republic in a government-to-government deal last year worth $125 million. Elta is a subsidiary of Israel Aerospace Industries. Israel has also inserted itself into the missiles market, among other products, in India, where there are several joint ventures. Israel is also a leader in multilayered air defense thanks largely to its Iron Dome and David's Sling systems, which Rafael co-produces with the American firm Raytheon. Elbit and other Israeli companies are also major suppliers of electro-optical technology. However, many Israeli defense deals are not made public, and the destination country for products is often not released. Israel says radars and electronic warfare suites made up 17 percent of the sales last year; missiles at 15 percent; and optics at 12 percent. Naval systems and vehicles were among the smallest portion of contracts. Slightly over 41 percent of sales were in Asia, while Europe and North America each accounted for a quarter of contracts. Africa and Latin America were both at 4 percent each. Israel historically sold UAVs and other items to Latin America and Africa, but the size of the purchases and lack of demand for the highest-end technologies appear to have led to minor contracts in these regions. Israel has been trying to turn the COVID-19 pandemic into an opportunity to work with foreign allies and partners, and not necessarily on defense but also medical needs. Israel's Defense Ministry says that Israel is among the top defense exporters in the world. Certainly per capita, the country is a global leader in defense exports. Up to 80 percent of its defense production is exported, according to the ministry. https://www.defensenews.com/global/europe/2020/06/22/israels-defense-export-contracts-were-worth-72-billion-in-2019

  • Saab fait voler une pièce de fuselage d’avion de combat imprimée en 3D

    Saab fait voler une pièce de fuselage d’avion de combat imprimée en 3D

    Le constructeur suédois Saab est parvenu, pour la première fois, à faire voler un avion équipé d'une pièce extérieure imprimée en 3D. L'avionneur utilise la technologie de la fabrication additive depuis quatre ans, notamment pour imprimer des pièces internes, précise L'Usine Nouvelle. La pièce, une trappe située sur le flanc arrière du fuselage de l'appareil, un modèle Gripen, a été imprimée sur la base du scan de la pièce originelle. Parfaitement ajustée à l'avion, elle n'a montré « aucun changement structurel visible après le vol d'essai », assure Hakan Stake, responsable du projet, dans un communiqué. Cette démonstration devrait, à terme, « permettre au personnel sur le terrain d'avoir accès à des pièces de rechange ajustées individuellement, d'éviter les réparations d'urgence ou de cannibaliser un appareil déjà endommagé », souligne-t-il. Il estime par ailleurs que cette solution permettra de réduire le nombre de pièces transportées lors du déploiement d'un appareil et de réduire son temps de réparation. De nombreuses étapes de certification du matériau utilisé, un polyamide 2200, couramment utilisé dans la fabrication additive, sont encore nécessaires avant de déployer la technologie sur le terrain.
